I need a extension cord with


I have a dedicated 20 circuit. The problem is that it’s only a duplex box and since I went back to mono blocks, I need more outlets. 
Does someone sell a high ish end cord with a good duplex box or a good quad box on the end? It’s mostly going to be used for power amps, so I don’t need any conditioning.

Thanks all.

Look at Panamax products

"Our power management products give your audio/video systems the pure, noise-free power they need for superlative performance, providing longevity to the components connected while protecting them from damage caused by power surges, dirty power, lightning and more."

Used Panamax items can be found on Ebay sometimes

 

 

Given some recent recommendations I’d reiterate the OP’s requirements that include no power conditioning and 20 amp compatibility just to avoid future wasted effort/time.

I second @audphile1 and the suggestion to simply a change your duplex box to a quad box.  Use whatever fancy (or not) outlets you want.  Depending on your current draw needs, service box capacity, and access, you could even run two dedicated lines to the two outlets, or not.  Either way, the most practical and least invasive(sonically) solution, IMO. Good luck.
